Could it be that the universe’s first structures were born not from enigmatic inflaton fields, but from the echoes of ancient gravitational waves? In a shocking shift from the conventional picture of ...

Every astronomy textbook tells us that soon after the Big Bang, there was a period of exponentially accelerating expansion called cosmic inflation. In a tiny fraction of a second, inflationary ...

Once upon a time, about 13.8 billion years ago, our universe sprang from a quantum speck, ballooning to one million trillion trillion trillion trillion trillion trillion times its initial volume (by ...

No definitive evidence for cosmic inflation is found, but support remains strong for the theory even as critics highlight its shortcomings as an explanation for how and why the universe began. Last ...

For a fraction of a second after the big bang occurred 13.8 billion years ago, most physicists believe, the newborn universe dramatically ballooned in size, jumping from being smaller than a proton to ...

TO COOK up planets, stars and people, the universe had to be preheated. In the first slivers of a second after the big bang, the universe expanded exponentially in a process called inflation, leaving ...

Here’s what you’ll learn when you read this story: Scientists have long been puzzled by why matter dominated antimatter in the early universe, when both should have been created equally and ...
